He also ensured Oxfam improved its safeguarding practices after the sexual abuse case by staff in Haiti in 2011, shortly after a devastating natural disaster in the country, Oxfam said.
Mark Goldring, who took up the post in 2013, was at the helm of the organisation when news broke of the sexual abuse of victims of the Haiti natural disaster in 2010 by then members of the charity's staff. "I am personally totally committed to seeing this phase through", he said, adding that next year, the charity would start trying to rebuild for the longer-term future.
'I think that this journey will best be led by someone bringing fresh vision and energy and making a long-term commitment to see it through'.
That led to many more allegations of abuse coming to light within Oxfam and across the wider aid sector, which faced heavy criticism as it was engulfed by the scandal.
Oxfam issued a full-page apology in The Guardian but Mr Goldring told the newspaper the charity was being attacked as if it had "murdered babies in their cots".
Caroline Thomson, the chair of Oxfam, said she had accepted Goldring's decision to step down "with great sadness and with thanks for his dedication and leadership".
The Oxfam scandal dominated the British national media for days, and attracted global publicity, but a spokeswoman for the charity said his resignation was "absolutely not to do with his handling" of the crisis.
It led to the resignation of the charity's deputy chief executive Penny Lawrence, who said she took "full responsibility" as programme director at the time and the loss of a number of high-profile ambassadors for the charity including the actress Minnie Driver and Archbishop Desmond Tutu.
"He rose to the enormous challenge and his leadership has been invaluable through it". At that point, Goldring said he would not step down unless the charity's board lost faith in his leadership. Goldring is expected to remain in his post until his successor is found.
